Got it installed on my 2022 F150 tremor 3.5 eco boost . It was the right inlet and outlet size. Muffler shop had to add a small piece of pipe because it’s shorter than stock but I knew that would be the case. Added a nice little rumble to the exhaust sound but not too loud and zero drone while cruising. Part of me wishes it was a bit louder but my wife is happy it’s not. Seems like a nice muffler for someone that wants a little exhaust noise but doesn’t want to piss off the neighbours

Great mellow rumble from my 5.3 Silverado. 00 drone. Running 1 in/2 out. Exiting behind the right rear tire. 90° turn down tips. No dirty looks from the neighbors yet so would seem I have struck the perfect note.

great sound with no drone noise at all.

Installed on a 5.0 small block ford in my Ranger. Each bank probably has less than 4 feet of tubing total and this muffler really helped to quiet it down, despite being a straight-through design. If you are looking for a loud exhaust this muffler isn't it, but it gives a nice deep tone and gets pretty loud when you step on it.

Sounds pretty good. Mounted to a 2017 toyota sequoia platinum 5.7 v8. Before mounting this I briefly ran a muffler delete and quickly realized that was a mistake. The sound was really good on the outside but the drone inside the cabin was too much for me, especially at higher speeds. Hence, I purchased this to get a balance between the sound I wanted without the loud drone. This muffler gave me the aggressive tone and rumble I wanted from the start. The start up and idle sounds almost the same as the muffler delete but when you get going you really see where it makes a difference. Furthermore, compared to the OEM muffler on the sequoia, this is a big upgrade in sound quality and exhaust flow. This unit is smaller and has a straight pipe design inside meaning I could look through one end and see straight out vs the OEM muffler which was not a straight pipe design. Note: I am running an MBPR exhaust tip (3 in to 5 out), the stock pipes and resonator on my set up.
